ROCK-CRUSHER.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed August 18, 1910. Serial No. 577,841.

To all whom it may concern:

Be it known that we, CHARLES G. SIMoNDs and ALBERT E. SMITH, citizens ofthe United States, residing at Milwaukee, in the county of Milwaukee andState of WVisconsin, have invented a new and useful Rock-Crusher, ofwhich the following is a specification.

The object of our invention is to provide a crusher in which the productis rapidly discharged being assisted in its exit by cen-. trifugalforce; to provide an extremely simple and compact machine, and one inwhich means is provided for readily adjusting the crusher heads to andfrom each other to compensate for wear and to vary the size of theproduct.

WVe attain these objects by the mechanism illustrated in theaccompanying drawings, in which three embodiments of the invention areshown, which drawings form a part of this specification.

Figure 1 is a vertical longitudinal section of the machine taken alongthe center line of the crusher shaft; Fig. 2 is a transverse sectiontaken on the line 12 Fig. 1; Fig.

3 shows a transverse section taken on the line 34: Fig. 1 and looking inthe direc-' tion of the arrow. Fig. 4B shows a vertical longitudinalsection taken along the center line of the crusher shaft of a modifiedform of the device; Fig. 5 is a transverse section on the line 12 ofFig. 4. Fig. 6 is a central longitudinal and vertical section of asecond modification of the device; and Fig.

17 is a transverse section taken on the line 12 of Fig. 6.

The same parts are given the same reference numerals throughout thedifferent views of the drawings.

The machine frame as shown in Fig. 1 consists of two essential parts, atube like part and a pedestal 51. These parts may be made separate andrigidly secured together or they may be made integral as shown. The tubeor barrel 50 carries interiorly an eccentric sleeve 52 which isvirtually a part of the frame during operation of the device. Thissleeve 52 affords two internal bearings 53 for the shaft 54 which Thematerial to be crushed is fed through the opening to the space betweenthe crusherheads 55 and 58. In this tapering are revolving, centrifugalforce will move the material away from the center, and when crushed fineenough to pass through the outlet between the crusher heads, thematerial will be thrown out and gathered by the trough or hood 61, whichcovers the opening between the flange 59 and the head 58 and leads tothe spout 62, through which the'material is finally discharged.

The eccentric sleeve 52 may be adjusted in the barrel 50 so that itseccentricity will augment or decrease the resultant eccentricity of thecrushing heads. This adjustment is for the purpose of giving the heads agreater relative movement when crushing spongy tough material, or asmallerrelative movement with attending greater force when crushing veryhard material. The sleeve 52 is secured in its adjusted position by thebolt 63 which may be engagedin any one of the holes 6 in the flange 66of the sleeve.

The head 58 is adjusted to or from the head 55 to compensate for wear orto materially change-the size of the product, by placing washers ofdifferent thickness on the bolts 68. These washers 67 may be U-shaped inorder that they may be removed or replaced without entirely removing thehead 58 or the bolts 68. In order to make the washers 67 more accessiblethe top half of the hood 61 is made removable.

It will be noted that'the horizontal component of the crushing strainwhich, in the machine shown in Fig. 1 is between one half and two thirdsof the total amount, is taken on the vertical bearing between 55 and 59,the reacting surfaces of which have only the small relative movement dueto the eccentricity of the heads. The vertical component of the crushingstrain acts upward on the bearing 65 and. is partly counter balanced bythe Weight of 58 and 59.

. The machine as shown in Figs. 4 and 5 does not differ inprinciple ormode of operation from the preceding form, nor does it differ verymaterially in construction. The

adjustable eccentric sleevelS is placed outside of the frame barrel ortube 11. This arrangement has the trifling disadvantage that as thesleeve 18 is adjusted, the'peripheries of the crusher member and flange16 will be varied relatively to the hood 27. Also the crusher heads 15and 19 must overhang the pedestal 10 more than in Fig.v 1 by thethickness of the flange 9.5 on the eccentric sleeve 18. Also'the bearingof the sleeve 18 is not so readily lubricated as in the form shown inlig; 1. Otherwise the two ployed with the form of crusher heads shown in:Fig. 1. In this form the outer hollow forms are about the: same. I InFigs. 6 and 7 we show a modlfied form of frame and mounting wlth aradically dlf- .ferent form of crushing heads. The mounting shown inFig. 6 may however be emshaft carries the driving pulley and if the formof heads shown in Fig. 1 were used the outer head would be directlydriven.

I The hollow shaftBO has twointernal bearings 32 running on a stationaryquill 38, and

one external bearing Bat journaled in the frame bearing The rear end ofthe, stationary quill-33 is supported in the frame bearing 36*and isprevented from turning.

in the frame by the bolt 37. The crusher shaft 38' has its bearing inthe stationary quill, said bearings being parallel with but eccentric tothe others. This form of frame, shafting and quill isin some respectspreferable to the formshown in Fig. lfrom the fact that the outersleeveh'a's' amuch larger bearing on the'ecc'entric stationary quill,and with the form .of heads of- Fig. 1 the outer and heavier head wouldbe directly driven leaving'the smaller head-to follow.

The crusher'heads-shown in Figs. 6 and 7 consist of flanges or webs 39and to, each carrying four inter-engaging lugs. These flanges arecarried respectively'by the internal shaft 38 andexternal hollow shaft30. The lugs (1 a a and a are carried by the internal shaft 38, the web39, and the hub 41'. The lugs 6 6 b and 6 are carried by the outer shaft30 and. the web 40. As

these shafts are parallel and eccentric the space between two adjacentlugs, as a and 72 will be at its minimum while the diametricallyopposite space,between a and 6 will be at its maximum, and all thespaces around thej arcs between these two will vary.

between these limits. The spaces between the lugs-taperdecreasingoutwardly, and centrifugal force will move the material untilit is caught and crushed between the lugs to finally escape" to thecollecting trough or chute 42 and be delivered thereby through theopening l3 in the base of the frame.
